Narrative:

I placed wooden chocks in front of my small aircraft antique biplane in preparation for starting the engine. The procedure for this engine is to depress the carburetor flooder valve, open the throttle and turn the engine through several revolutions, close the throttle and turn the engine several revolutions in reverse with throttle closed, switch on mags and start engine. On this date after turning the reverse revolutions the throttle was not fully closed and when the start was attempted, the engine fired and started. The aircraft could not be held back and left my control. It had an adjacent hangar door and stopped. Fortunately, there were no personal injuries or damage to property of others. This did not result in an accident under NTSB. The event could have been prevented by having the aircraft tied down, having a pilot familiar with this aircraft in the cockpit and by having an assistant stand along side the plane within reach of the magnetic switches located externally. I will follow these procedures in the future and will suggest them to all operators of similar types of aircraft.

Original NASA ASRS Text

Title: PLT OF ANTIQUE SMA BIPLANE PERFORMING A HAND PROP FAILS TO PLACE THROTTLE IN THE APPROPRIATE POSITION, FAILS TO TIE DOWN ACFT, AND FAILS TO HAVE ANOTHER PLT ATTEND THE BRAKES. ACFT JUMPS CHOCKS AND TAXIS OUT OF CTL INTO HANGAR DOOR.

Narrative: I PLACED WOODEN CHOCKS IN FRONT OF MY SMA ANTIQUE BIPLANE IN PREPARATION FOR STARTING THE ENG. THE PROC FOR THIS ENG IS TO DEPRESS THE CARB FLOODER VALVE, OPEN THE THROTTLE AND TURN THE ENG THROUGH SEVERAL REVOLUTIONS, CLOSE THE THROTTLE AND TURN THE ENG SEVERAL REVOLUTIONS IN REVERSE WITH THROTTLE CLOSED, SWITCH ON MAGS AND START ENG. ON THIS DATE AFTER TURNING THE REVERSE REVOLUTIONS THE THROTTLE WAS NOT FULLY CLOSED AND WHEN THE START WAS ATTEMPTED, THE ENG FIRED AND STARTED. THE ACFT COULD NOT BE HELD BACK AND LEFT MY CTL. IT HAD AN ADJACENT HANGAR DOOR AND STOPPED. FORTUNATELY, THERE WERE NO PERSONAL INJURIES OR DAMAGE TO PROPERTY OF OTHERS. THIS DID NOT RESULT IN AN ACCIDENT UNDER NTSB. THE EVENT COULD HAVE BEEN PREVENTED BY HAVING THE ACFT TIED DOWN, HAVING A PLT FAMILIAR WITH THIS ACFT IN THE COCKPIT AND BY HAVING AN ASSISTANT STAND ALONG SIDE THE PLANE WITHIN REACH OF THE MAG SWITCHES LOCATED EXTERNALLY. I WILL FOLLOW THESE PROCS IN THE FUTURE AND WILL SUGGEST THEM TO ALL OPERATORS OF SIMILAR TYPES OF ACFT.
